Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Primary Hypothesis: Differing the catheter insertion site (femoral vs. psoas compartment) for a perineural local anesthetic infusion is not associated with lower pain scores during the 24-hour period beginning the morning following hip arthroplasty.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
1. Femoral Nerve Block
Patients will be randomized with a computer program to receive a femoral catheter. The catheter will be placed using standard technique. The time of catheter placement will be recorded as well as the pain/discomfort of catheter placement as reported by the patient on a 0-10 scale where 0=no pain/discomfort and 10=worst imaginable pain/discomfort.
Femoral Nerve Block vs. Psoas Compartment Nerve Block
Patients, undergoing hip arthroplasty or hip resurfacing will be randomized to one of two groups: femoral nerve block or psoas compartment nerve block. Patients randomized to femoral nerve block will receive this block prior to surgery. Patients randomized to psoas compartment nerve block will receive this block prior to surgery. Both patients will receive Mepivicaine via catheter prior to surgery and following surgery, Ropivicaine via pain pump.
2. Psoas Compartment Catheter
Patients will be randomized with a computer program to receive a psoas compartment catheter. The catheter will be placed using standard technique. The time of catheter placement will be recorded as well as the pain/discomfort of catheter placement as reported by the patient on a 0-10 scale where 0=no pain/discomfort and 10=worst imaginable pain/discomfort.
